Intel Celeron D Processor

The Celeron processor is a budget processor offering moderate performance at an affordable price. This processor is suitable for use in notebook and desktop computers running home-office applications and providing access to the Internet. It is not be recommended for use in a high performance game machine or a heavily accessed web server.

The Celeron D processor, released in December 2005, is based on the Prescott core. It runs at clock speeds up to 3.33 GHz, has a 533MHz Front Side Bus Speed, a 16kb L1 cache, and an integrated 256K L2 cache. Celeron D models 347 and higher use the 65nm Cedar Mill core and have a 12KB + 16KB (Data + Instructions) L1 Cache and a 512KB L2 cache.

This processor uses either the socket 478 or the LGA775 Socket. The two socket types are not interchangeable because the newer 775-pin Land Grid Array has no pins on the processor. Gold contact pads provide the connection between the processor and the socket on the motherboard.

Some Celeron D models feature Intel's Extended Memory 64 Technology which allows them to access larger amounts of memory and support 64-bit extended operating systems. Some models, including those with J in their model number, feature the Execute Disable Bit (XDB), which prevents viruses from exploiting buffer overrun vulnerabilities.

Don't confuse the Celeron D with processors without the "D", which are based on the Northwood core and have only 8kb of L1 cache and a 128 KB L2 cache.

Note that, unlike the Pentium D, the Celeron D is not a dual core processor.
